时间是一切财富中最宝贵的财富。—— 德奥弗拉斯多
今天分享下使用的一个小技巧：
<PHAsset: 0x7feb5bd95e00> 9F983DBA-EC35-42B8-8773-B597CF782EDD/L0/001 mediaType=1/0, sourceType=1, (3000x2002), creationDate=2012-08-08 18:52:11 +0000, location=1, hidden=0, favorite=0
上面是使用QBImagePicker选取一张图片后的详细信息。添加图片根据图片的基本信息存入一个数组，通过数组判断图片是否重复添加：
- (void)qb_imagePickerController:(QBImagePickerController *)imagePickerController didFinishPickingAssets:(NSArray *)assets{
if (imagePickerController.mediaType == QBImagePickerMediaTypeImage) {//判断是否是图片
NSMutableArray *imageArray = [NSMutableArray array];
for (PHAsset *set in assets) {
NSString * str = set.description;//获取图片基本信息
NSString * st = [str substringWithRange:NSMakeRange(26, 36)];//截取图片标识码进行存储识别
if ([self.assets_array containsObject:st]) {// 包含图片
} else { // 不包含
[self.assets_array addObject:st];//self.assets_array 存储图片识别码
PHImageRequestOptions *options = [[PHImageRequestOptions alloc] init];
options.synchronous = YES;
options.deliveryMode = PHImageRequestOptionsDeliveryModeHighQualityFormat;
[[PHImageManager defaultManager] requestImageForAsset:set targetSize:[UIScreen mainScreen].bounds.size contentMode:PHImageContentModeAspectFit options:options resultHandler:^(UIImage *result, NSDictionary *info) { if (set.mediaSubtypes == PHAssetMediaSubtypePhotoLive) { //获取图片
UIImage * image = [result scaleImageWithSize:CGSizeMake(1280, 960)];
[imageArray addObject:image];
} else {
[imageArray addObject: result];
}
}];
}
}
//进行自己的UI逻辑
}
}
/**
设置QBImagePiker
@param modeType 存储类型
@param promptStr 标识
@param maxContent 最大选取数
@param viewController
*/
- (void) addQBImagePikerWithType:(QBImagePickerMediaType) modeType withPromt:(NSString * )promptStr withMax:(NSInteger) maxContent withViewController:(UIViewController *) viewController{
QBImagePickerController * imagePickerIM = [QBImagePickerController new];
imagePickerIM.delegate = viewController;
imagePickerIM.mediaType = modeType;
imagePickerIM.prompt = promptStr;
imagePickerIM.showsNumberOfSelectedAssets = YES;
imagePickerIM.allowsMultipleSelection = YES;
imagePickerIM.maximumNumberOfSelection = maxContent;
}
今天比较忙写的不是很好，大家见谅！
